Knitted fabrics use knitting needles to bend yarns into loops and string them together. The fabric formed. Knitted fabrics are divided into weft knitted fabrics and warp knitted fabrics.
Basic structure of weft knitted fabric
Basic structure of warp knitted fabric
Weft knitted fabric first of all It is woven widthwise. And it is formed by one continuous yarn being tied into loops.
Weft-knitted fabrics are easier to produce, but they are also more likely to unravel when cut.
Warp knitted fabric is usually lengthwise, and its organization is unfolded in a zigzag shape. , so that it can make the coil form two or more continuous wales. Compared with weft knitted fabrics, it is usually flatter and has a tighter structure, which results in less elasticity and prevents run-off.
resistant).
Characteristics of knitted fabrics
( 1) Scalability. Knitted fabric is made of yarns bent into loops and strung together. The loops have a large room for expansion and contraction up and down, left and right, so they have good elasticity, fit and follow the body when worn, are comfortable and convenient, and are suitable for stretching and stretching during human movement. bending and other requirements.
(2) Softness. The raw materials used in knitted clothing fabrics are fluffy, soft yarns with small twists. There is a layer of tiny suede on the surface of the fabric. In addition, the tissue composed of coils is loose and porous, which reduces the friction between the skin and the surface of the fabric when worn. Gives people a feeling of comfort and gentleness.
(3) Hygroscopicity and breathability. Because the coils that make up the knitted fabric are intertwined with each other, countless isolated air pockets are formed inside the fabric, which has good warmth retention and breathability. In addition, both plant and animal fibers have a certain ability to absorb moisture, especially cotton fiber, which has better moisture absorption properties. Therefore, wearing cotton knitted clothing in summer feels cooler without feeling stuffy and uncomfortable.
(4) Anti-wrinkle. When the knitted fabric is subjected to external wrinkle forces, the loops can be transferred to adapt to the deformation when the force is applied; when the wrinkle force disappears, the transferred yarn can quickly recover and maintain its original state.
Common knitted fabrics
01
Knit
King cloth is composed of continuous loops, with the front side The texture is clearer than the texture on the back and is easy to identify.
The cloth surface is smooth and the texture is clear. The texture is fine, smooth to the touch, and has good longitudinal and transverse extensibility, and the transverse extensibility is greater than the longitudinal extensibility. It has good hygroscopicity and air permeability, but it has detachment and curling properties, and sometimes coil distortion occurs.

Piqué mesh
Piqué mesh fabric is made of continuous It consists of Knit stitch and Tuck stitch, including 4-mode single bead, 6-mode bead, 8-mode bead, twill bead, sports bead, spandex bead, etc.
△4 mode beige
△6 mold beads The characteristic of ground is that it consists of one continuous circle and two tuck circles on the same longitudinal road. composition.

Sweatshirt cloth
Sweatshirt fabric is a kind of knitted fabric, which is French in English
terry, called fleece after hair pulling. This type of knitted fabric is mostly made of displacement yarn, so it is called displacement fabric or sweatshirt fabric. In some places it is called terry cloth, and in other places it is called fish scale cloth. There are many varieties. (Fish scale cloth is named because the back of the cloth is terry, and some look like fish scales.) The weight is generally 190g/M2 -350g/M2.
04
Ribbed cloth
Rib knitted fabric is a knitted fabric in which a single yarn forms wales of loops on the front and back sides. Rib knitted fabric has the detachability, hemming and extensibility of plain weave fabric, while also having greater elasticity.
1×1 rib looks similar to plain weave , but the rib structure is loose, the elasticity is greater, and generally there is no distinction between front and back.
And other structures of ribs such as 2×2, 2×1 Structure, etc., due to the particularity of its structure, it is easy to distinguish it from other fabrics.

Roman cloth
Roman cloth is a knitted fabric, weft knitted, and made on a double-sided circular knitting machine. Also called ponte-de-roma, commonly known as chicken-beating cloth. Roman cloth is a four-way loop. The cloth surface is not as smooth as ordinary double-sided cloth, but has slightly irregular horizontal stripes. The fabric has good elasticity both horizontally and vertically, but its horizontal stretch performance is not as good as double-sided fabric and it has strong moisture absorption. Used to make close-fitting clothing, breathable, soft and comfortable to wear.
It is easy to distinguish it from other fabrics.
